Lithophyllum is a genus of thalloid alga comprising 120 species. The monomerous, crustose thalli are composed of a single system of filaments which grow close to the underlying surface. Lithophyllum reproduces by means of conceptacles. The epithallus is periodically shed to avoid organisms growing on top of the alga.[1]
